  • Publication number: 20190224746
    Abstract: A steering-wheel core eliminating or reducing the need to perform finishing processing after casting and decreasing a manufacturing cost even when the steering-wheel core is cast using a molten metal process. The steering wheel core includes a boss core portion coupled to a steering shaft, a rim core portion and a spoke core portion. The boss core portion forms a nut seat surface that makes contact with a nut when the nut is fastened to a distal end of the steering shaft. A recess is formed in the nut seat surface depressed toward a back surface side of the boss core portion. The recess is preferably provided in an annular form so as to surround the circumference of the nut seat surface.

  • Publication number: 20180211453
    Abstract: Reception unit receives data indicating water temperature of a body of water through which a vessel voyages, vessel speed, and a period for which those values are maintained. From storage unit, index value acquisition unit reads out a decrease amount of anti-fouling paint corresponding to the water temperature and vessel speed received by reception unit. Index value specification unit specifies a decrease amount of anti-fouling paint in the period by multiplying the length of time of the period received by reception unit by the decrease amount read out by index value acquisition unit. Remaining amount acquisition unit integrates the decrease amounts of the anti-fouling paint specified by index value specification unit at the time of coating with the anti-fouling paint and onward.

  • Publication number: 20180181316
    Abstract: Apparatuses are coupled to each other to enable data de-duplicated by post-process processing or inline processing to be stored in a distributed manner into storage devices provided for the apparatuses. An apparatus stores apparatus-information identifying the apparatuses and performance-information of the post-process processing and the inline processing. Upon receiving an instruction for storing target-data into a storage destination, the apparatus calculates, based on a size of the target-data, the performance-information, and the apparatus-information, a first-size of first-data for the post-process processing and a second-size of second-data for the inline processing such that latency by the post-process processing and latency by the inline processing are balanced with each other.
